Description

Technical Field

[0001] This utility model relates to the field of pottery throwing technology, and in particular to a pottery throwing device for porcelain production. Background Technology

[0002] Water is needed to moisten the clay in the process of making porcelain blanks using pottery throwing equipment, in order to improve the smoothness of the surface and ensure the quality of the shaping. Existing pottery throwing equipment typically lacks a water-holding structure; instead, a water container is placed on the side of the equipment during operation. This not only occupies floor space outside the equipment but also makes it difficult for workers to reach the water by hand. Furthermore, since workers' hands are in prolonged contact with the clay during the throwing process, there is a risk of clay falling onto the ground when workers reach the container outside the equipment to get water, increasing the burden of subsequent cleanup. Therefore, there is an urgent need for a porcelain throwing device that allows for convenient water access and reduces the space occupied by the equipment. Utility Model Content

[0003] The purpose of this utility model is to provide a pottery throwing device for porcelain production, which is convenient for water intake during the throwing process, reduces the occupation of external ground space, and also reduces the amount of clay falling onto the ground. It has a simple structure and strong practicality.

[0004] The present invention adopts the following technical solution:

[0005] A pottery throwing device for porcelain production includes a pottery throwing machine body, a turntable mounted on the pottery throwing machine body, and a protective cover coaxially mounted on the outside of the turntable. The protective cover is composed of two separate outer shells joined together. An annular water-holding tray is coaxially fitted on the outside of the protective cover. Two sets of sliders are radially symmetrically arranged on the inner wall of the water-holding tray near the inner wall of the protective cover. The two sliders in each set are symmetrically arranged on both sides of the axis of the water-holding tray. Positioning protrusions are provided on both sides of the two outer shells of the protective cover at their opposite ends. The two sliders in each set are slidably fitted on the two positioning protrusions on the corresponding sides.

[0006] Preferably, the positioning protrusion is arranged along the height of the protective cover, and its length is not less than the height of the protective cover.

[0007] Preferably, the outer side of the positioning protrusion is provided with a groove for the slider to slide.

[0008] Preferably, the inner wall of the water-holding tray is provided with an mounting plate, and the slider is elastically disposed on the mounting plate.

[0009] Preferably, the slider is provided with a ball bearing.

[0010] Preferably, the top of the water-holding tray is provided with a water-absorbing balloon, the bottom port of which corresponds to the location of the water-holding trough of the water-holding tray, and a flexible water pipe is externally connected to it.

[0011] Preferably, the bottom of the absorbent bulb is provided with a retractable hose.

[0012] Preferably, a spherical filter screen is connected to the bottom end of the hose.

[0013] Preferably, the water-holding tray is provided with a support plate that can slide along its circumference, and the water-absorbing balloon is disposed on the support plate.

[0014] Preferably, the water tank in the water-holding tray is provided with a drain hole, the drain hole is provided with a sealing plug, and a drain pipe is connected to the bottom of the drain hole.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: By coaxially fitting a ring-shaped water-holding tray outside the protective cover, this utility model integrates the container for holding the water needed for throwing the potter's wheel into the perimeter of the protective cover, avoiding the occupation of ground space outside the equipment; in addition, the ring-shaped water-holding tray can form a through-hole ring-shaped water storage space around the protective cover, making it convenient for workers to fetch water from the left or right side according to their own habits. At the same time, the coaxial fitting of the water-holding tray outside the protective cover shortens the water-fetching distance, reduces the probability of clay falling from the workers' hands to the ground during water fetching, keeps the ground clean, and reduces the difficulty of subsequent ground cleaning.

[0019] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:

[0020] like Figures 1 to 3As shown, the present invention discloses a pottery throwing device for porcelain production, comprising a pottery throwing machine body 1, a turntable 2 mounted on the pottery throwing machine body 1, and a protective cover 3 coaxially mounted on the outside of the turntable 2. In the prior art, the protective cover 3 is usually composed of two separate outer shells joined together. A ring-shaped water-holding tray 4 is coaxially mounted on the outside of the protective cover 3. Both the water-holding tray 4 and the protective cover 3 are preferably configured with a circular cross-section. A ring-shaped water-holding groove 5 is formed on the water-holding tray 4 along the circumferential direction. Two sets of sliders 6 are symmetrically arranged radially on the inner wall of the water-holding tray 4 near the protective cover 3, with two sliders 6 in each set symmetrically arranged on both sides of the axis of the water-holding tray 4. The two sides of the two outer shells of the protective cover 3 protrude outwards at the opposite end. The device is equipped with positioning protrusions 7, and two sliders 6 in each group slide and fit over the two positioning protrusions 7 on the corresponding sides. This not only enables the water tray 4 to be fitted with the protective cover 3, but also further reinforces the split protective cover 3. During operation, water is placed directly into the water tank 5, which avoids occupying open space outside the equipment and provides convenience for workers to access the water. It can meet the needs of people with different preferences to access the water from the left or right side. At the same time, since a small amount of water is usually sprinkled onto the blank by hand during the throwing process, the optimized setting of this application shortens the water access distance, reduces the amount of water spilled when using hands to access the water, and also reduces the probability of clay falling from the hands to the ground, making it highly practical.

[0021] Furthermore, in this embodiment, the positioning protrusion 7 is arranged along the height of the protective cover 3, and its length is not less than the height of the protective cover 3, so as to ensure that the length of the positioning protrusion 7 provides adjustment margin for the vertical movement of the water tray 4, thereby meeting the setting of the water tray 4 at different heights and further matching the usage needs of different users. Preferably, a sliding groove 8 is provided on the outer side of the positioning protrusion 7 to provide guidance for the installation of the slider 6 outside the positioning protrusion 7, improving the convenience of installation and disassembly of the water tray 4.

[0022] Furthermore, the inner wall of the water-holding tray 4 is provided with a mounting plate 9, and the slider 6 is elastically mounted on the mounting plate 9. Specifically, a receiving sleeve can be provided on the mounting plate 9, and the slider 6 is movably mounted in the receiving sleeve by a spring; alternatively, a through hole can be opened through the mounting plate 9, and the slider 6 is movably mounted through the through hole by a spring. The specific configuration can be flexibly set according to actual needs. When the slider 6 enters the slide groove 8, the spring is in a compressed state, so that the slider 6 and the slide groove 8 are in close contact, ensuring the stability of the position of the water-holding tray 4. Preferably, a ball bearing 10 is movably mounted on the slider 6, and the ball bearing 10 is movably located in the slide groove 8. The ball bearing 10 helps to reduce the wear generated between the slider 6 and the slide groove 8 when sliding; however, under the action of the spring restoring force, the ball bearing 10 is tightly attached to the slide groove 8, and under the action of the spring restoring force, the friction between the ball bearing 10 and the slide groove 8 is greater than the total weight of the water-holding tray 4 after it is filled with water, reducing the probability of the water-holding tray 4 sliding down during use.

[0023] Furthermore, a water-absorbing ball 11 is provided on the top of the water-collecting pan 4, with the bottom of the water-absorbing ball 11 corresponding to the position of the water-collecting trough 5 of the water-collecting pan 4, and a flexible water pipe 12 is externally connected to it. The function of the water-absorbing ball 11 is to help draw water droplets that have spilled into the protective cover 3 into the water-collecting trough 5, so as to prevent water remaining inside the protective cover 3 from spilling onto the top of the potter's wheel body and flowing into the rotating shaft of the turntable 2, which could cause corrosion of the rotating shaft. In use, simply squeeze the water-absorbing ball 11 to expel the internal gas, and the water in the protective cover 3 can be drawn out under the action of pressure difference; preferably, the bottom of the water-absorbing ball 11 is provided with a retractable flexible hose 13, which can be easily extended into the water-collecting trough 5 below the liquid surface. After the blank is made, the water in the water-collecting trough 5 can be drawn out by squeezing the water-absorbing ball 11 to rinse the turntable 2. When it is necessary to draw out the water in the protective cover 3, the flexible hose 13 is compressed upwards and returned to its original position, so that it can be pulled out from the liquid surface in the water-collecting trough 5. In addition, as Figure 3 As shown, a spherical filter screen 14 is also connected to the bottom of the hose to prevent the mud particles that fall into the water tank 5 during water suction from being sucked out and falling back onto the turntable 2, thus re-contaminating the turntable 2. The filter screen 14 is preferably designed as a spherical structure to increase the filtration area and ensure the water suction rate.

[0024] Furthermore, the water-holding tray 4 is provided with a support plate 15 that can slide along its circumference. Specifically, the outer side of the water-holding tray 4 has a protruding edge, and the bottom of the protruding edge has an annular track groove along its circumference. The support plate 15 is as follows: Figure 3 The U-shaped structure shown has guide balls 16 movably disposed on its bottom top surface, and the guide balls 16 slide within the track groove; the water-absorbing ball 11 is disposed on the support plate 15; this arrangement facilitates the adjustment of the position of the water-absorbing ball 11, thereby meeting different usage needs.

[0025] In this embodiment, a drain hole 17 is also provided in the water tank 5 inside the water tray 4. A sealing plug is provided on the drain hole 17, and the sealing plug seals the drain hole 17 in the working state. A drain pipe 18 is connected to the bottom of the drain hole 17. The drain pipe 18 is preferably a flexible hose, which is convenient to put into the collection device for water discharge when draining. Of course, in this embodiment, the water tray 4 can also be removed as a whole to pour out the internal water flow as needed. When there is not much dirt in the water tray 4, the turntable 2 and the protective cover 3 and no cleaning is required, the sealing plug can be removed and the drain pipe 18 can be used to drain the water, which further enhances the practicality of this utility model.
